Work on the "Garnishes" tab

[rodluger]

Place the checkboxes in the "appearance" tab within a Div with a nice border (as in the "data" tab) to maintain a consistent styling.

Add more tools, such as:

• [ ] colormap picker for the marker color scheme
• [ ] scale (all) the marker sizes up or down
• [ ] change marker opacity (alpha) etc.

Renamed "appearance" to "Garnishes". Enforcing correct style now.
